Thus, avoided inherited under-segmentation defects of thresholding-based methods when dealing with more complicated COVID-19 lung regions. The corresponding pseudocode is summarized in Algorithm 1. Algorithm 1. Pseudocode code of unsupervised refinement method. Given the limited engagement of radiologists ...
The use of clustering in supporting customer segmentation to improve the performance of machine learning techniques is not new. Jafari-Marandi et al. [29] have also explored the use of clusters to improve the prediction accuracy. However, this approach combined with the use of survival models, ...
Wrist-worn sensors have better compliance for activity monitoring compared to hip, waist, ankle or chest positions. However, wrist-worn activity monitoring is challenging due to the wide degree of freedom for the hand movements, as well as similarity of
